MetaTrader 5 Strategy Tester: bugs, bugs, suggestions for improvement - page 39

If you are debugging a script or an EA and roam around the collstack, a green arrow appears on the left side of the source code, showing which line you are on. If you roam the collstack in different files, for example many different inludes, in fact each open tab with its own file will have a different green arrow. But when I stop debugging, they don't disappear, but stay there. Bug or bug?
 
I don't know if this has already been mentioned in this thread or not. Maybe they will finally make access to all available bars from the tester? I'm really sick and tired of working on 5 minutes to load older TFs over several years through crutches!

A build of 2280 is used. It takes a symbol and a period when there were no quotes on it. In this case it is stock exchange, broker Otkritie, symbol UCAD-12.19, period 01.09.2019-03.09.2019. A simple Expert Advisor is running (below). If you race it one pass at a time, it's fine, it just says no history, 0 bars and 0 ticks. If I run optimization, it will not matter if it is genetic or full, the log will contain a lot of errors

It seems to be a response to access theOldTicks array, but I don't know why. Replacing the function return result with the array size doesn't help. What to do about it is unknown.

To reproduce and fix this error we need an expert in the form of ex5 and optimization conditions.

If it is not a problem for you, please send it to me in a private message. The expert will be irretrievably wiped out after the research

The source code of the Expert Advisor is given in the same post. Just in case, I posted it again below.

The symbol and period, when there were no quotes on it. In my case it is stock exchange, broker Otkritie, symbol UCAD-12.19, period 01.09.2019-03.09.2019.

Genetic optimisation or complete overshoot-doesn't matter. By a single variable test, more passes, put from 0 to 1000000.

input int test=1;

double OnTester()
{
  return 0;
}

void Test(const MqlTick &Tick)
{
}

void OnInit()
{
  MqlTick OldTicks[];
  int OldTicksCount=CopyTicks(_Symbol,OldTicks,COPY_TICKS_ALL);
  while(OldTicksCount>=1000)
    OldTicksCount=CopyTicks(_Symbol,OldTicks,COPY_TICKS_ALL,OldTicks[OldTicksCount-500].time_msc);
  for(int i=0;i!=ArraySize(OldTicks);++i)
    Test(OldTicks[i]);
}

Thanks for the message!

After the highlighted line, pressed Stop. Terminal entered "Not responding" mode. It hung up after 27 seconds (judging by the log).
 
How do you calculate the number of all errors from a single EX5 run? For example, wrong lot or lack of margin.
 
Bild 2280. It takes a symbol and a period when there were no quotations on it. In this case it is a stock exchange, broker Otkritie, symbol 1MFR-1.20, period 01.09.2019-01.12.2019. Runs any Expert Advisor, say from Examples\Moving Average\Moving Average.ex5. Genetic optimization is set (although I suspect others have this bug as well), criterion makes no difference (no ticks anyway), each tick based on real ticks, profit in pips. We optimize it and get essentially a set of zero passes. Why are profit_factor and margin_level filled with rubbish in each pass? Aren't the variables initialized with zero somewhere? In the backtest tab it just looks like an empty space, it doesn't output anything. If we parse the opt-file by hand, the values are profit_factor = 1.797693134862316e+308 and margin_level = 1.797693134862316e+308.
